[zod-openapi] - OpenAPI 3.0: invalid exclusiveMinimum / exclusiveMaximum

[RobbyUitbeijerse]

Hi there!

We just found another small issue with the OpenAPI 3.0 output, here's a diff I shared in the other issue regarding the nullable parsing: https://www.diffchecker.com/Zg4nfCdt/

In OpenAPI 3.0, the exclusiveMinimum is expected to be returned as a boolean, while in 3.1 the property can be a number. Currently, when passing down 3.0 in the patchNestjsSwagger, the

expected

"exclusiveMinimum": true,

What we receive (which is correct in 3.1, but invalid in 3.0)

"exclusiveMinimum": 0
